In a column published on its premium Packer Insider page, the Milwaukee Journal Sentinel reported the Green Bay Packers have evidence that quarterback Brett Favre made "repeated calls" not only to Minnesota Vikings offensive coordinator Darrell Bevell, but also to coach Brad Childress.

The Packers filed tampering charges against the Vikings earlier this month, and the NFL is investigating. The Vikings haven't commented, but according to the Journal Sentinel, Favre held the conversations with both men on a cell phone issued by the Packers. Because they owned the number, the Packers were able to review Favre's phone records and make the discovery.

As many have pointed out, telephone calls alone are not evidence of tampering. Neither are conversations between two men -- Bevell and Favre -- who have known each other for most of this decade. But the more widespread the contact -- Childress and Favre have no direct history with each other -- the harder it will be for the NFL to look past the accusations.
